In the related prior art, a neural network processor uses an interrupt mechanism to perform exception processing, which takes too much time and lowers down the data processing efficiency of the entire neural network hardware system.

FIG. 1(a) is a structural schematic diagram of an electronic equipment provided by an exemplary embodiment of the present disclosure. As can be seen from FIG. 1(a), in the present disclosure, an electronic equipment 100 may comprise: 4 types of error detectors, i.e., a bus and interface error detector 111, a storage unit error detector 121, a timeout error detector 130, and a calculation error detector 141; wherein, the bus and interface error detector 111 is used to detect errors in the bus and interface, such as response errors, integrity errors, and/or protocol errors; the storage unit error detector 121 is used for error checking and correction (Error Correcting Code; hereinafter referred to as: ECC) of a Random Access Memory (hereinafter referred to as RAM), a First Input First Output (hereinafter referred to as FIFO), and/or a register file; the timeout error detector 130 is used to detect timeout errors; and the calculation error detector 141 is used to detect errors regarding such as multiplication and/or addition.

In addition, the electronic equipment 100 may further comprise a neural network processor 180, which can obtain errors detected by the above-mentioned error detectors.

Specifically, the electronic equipment 100 may be a smart electronic equipment such as a smart phone, a tablet computer, a personal computer (PC), or a vehicle-mounted smart device and the like. The specific form of the electronic equipment 100 is not limited in this embodiment.

In the present disclosure, the electronic equipment 100 generates an exceptional signal according to an error detected by the error detectors, during an operation, then according to the exceptional signal, the electronic equipment 100 determines an exception processing instruction corresponding to the exceptional signal, and acquires a first instruction queue needed to be executed by the electronic equipment 100 from the instruction queue buffer 160 in the electronic equipment 100, and then according to the exception processing instruction, the electronic equipment 100 determines processing priority corresponding to the exception processing instruction, and finally the electronic equipment 100 inserts the exception processing instruction into the first instruction queue according to the processing priority to generate a second instruction queue, and executes the second instruction queue, so that errors encountered by the electronic equipment 100 can be processed timely, shortening the error processing delay of the electronic equipment 100, and improving the data processing efficiency of the hardware system in the electronic equipment 100.

FIG. 1(b) is a structural schematic diagram of an electronic equipment provided by another exemplary embodiment of the present disclosure. As can be seen from FIG. 1(b), the electronic equipment 100 may comprise a neural network processor 180, which may comprise 4 types of error detectors, namely the bus and interface error detector 111, the storage unit error detector 121, the timeout error detector 130, and the calculation error detector 141; that is, in this embodiment, the neural network processor 180 is a System On a Chip (hereinafter referred to as SOC).

FIG. 2 is a schematic flowchart of an instruction execution method provided by an exemplary embodiment of the present disclosure. This embodiment can be applied to the electronic equipment 100. Referring to FIG. 1(a) to FIG. 1(b), the electronic equipment 100 comprises the neural network processor 180.

As shown in FIG. 2, the method may include Step 201: acquiring an exceptional signal generated by a neural network processor during an operation.

The exceptional signal is generated by the electronic equipment 100 based on various errors detected by the error detectors in FIG. 1 (a)-FIG. 1 (b). Various errors detected by the error detectors may comprise: (a) a bus and interface error detected by the bus and interface error detector 111, such as a response error, an integrity error, and/or a protocol error, etc.; (b) a RAM and/or FIFO error detected by the storage unit error detector 121; (c) a timeout error detected by the timeout error detector 130; and (d) a multiplication and/or addition error detected by the calculation error detector 141.

The above-mentioned errors are only a few examples of errors detected by the error detectors in the electronic equipment 100. Of course, other errors may also occur during the operation of the electronic equipment 100, which is not limited in this embodiment.

Step 202: according to the exceptional signal, determining an exception processing instruction corresponding to the exceptional signal.

Specifically, the exception processing instruction is used to process the exceptional signal generated by the neural network processor 180 during an operation. For example, assuming that the exceptional signal is generated based on the bus and interface error detected by the bus and interface error detector 111, then the exception processing instruction corresponding to the exceptional signal may be an instruction to close the interface; and assuming that the exceptional signal is generated based on an error resulted from such as multiplication and/or addition detected by the calculation error detector 141, the exception processing instruction corresponding to the exceptional signal may be an instruction to shut down the computing unit in which the error occurred, and/or an instruction to adjust the mapping relationship of the computing unit.

Step 203: determining a first instruction queue needed to be executed by the neural network processor.

The first instruction queue comprises a plurality of instructions that need to be executed during the operation of the neural network processor 180 when no exceptional signal is detected.

Step 204: generating a second instruction queue according to the exception processing instruction and the first instruction queue.

Specifically, after detecting the exceptional signal and determining the exception processing instruction corresponding to the exceptional signal, the electronic equipment 100 may insert the exception processing instruction into the first instruction queue to generate a second instruction queue.

For example, assuming that the first instruction queue comprises the following instructions: N0, N1, N2, . . . , Nn, and the neural network processor 180 sequentially executes the instructions N0, N1, N2, . . . , Nm in the first instruction queue, and assuming that when the neural network processor 180 executes the Nm instruction, the bus and interface error detector 111 detects that the neural network processor 180 encounters a bus and interface error, and the electronic equipment 100 generates an exceptional signal based on the error detected by the bus and interface error detector 111, and determine that an exception processing instruction corresponding to the exceptional signal is an instruction Ama to close the interface, then the electronic equipment 100 generates a second instruction queue according to the instruction Ama to close the interface and the first instruction queue, wherein the second instruction queue is N0, N1, N2, . . . , Nm, Ama, Return, No, Np, . . . , Nn.

Step 205: executing the second instruction queue.

In the above instruction execution method, after acquiring the exceptional signal generated by the neural network processor during its operation, the electronic equipment 100 determines the exception processing instruction corresponding to the exceptional signal according to the exceptional signal, and then it determines the first instruction queue required to be executed by the neural network processor, and generates the second instruction queue according to the exception processing instruction and the first instruction queue, and finally it controls the neural network processor to execute the second instruction queue, so that errors encountered by the neural network processor can be processed in time, thereby shortening the error processing delay, and improving the data processing efficiency of the neural network hardware system in the electronic equipment 100.

FIG. 3 is a schematic flowchart of an instruction execution method provided by another exemplary embodiment of the present disclosure. This embodiment can be applied to the electronic equipment 100. Referring to FIG. 1(a) to FIG. 1(b), the electronic equipment 100 comprises the neural network processor 180.

As shown in FIG. 3, the embodiment of the present disclosure may include Step 301: acquiring first identification information corresponding to an exceptional hardware module from the exceptional signal.

The first identification information may be a mark of the exceptional hardware module, which is used to indicate the exceptional hardware module.

Step 302: acquiring the hardware module corresponding to the first identification information from the neural network processor.

Specifically, since the first identification information may be the mark of the exceptional hardware module, the electronic equipment 100 can obtain the hardware module corresponding to the first identification information from the hardware modules comprised in the electronic equipment 100 itself according to the first identification information.

Step 303: acquiring second identification information for indicating that the above-mentioned hardware module is exceptional, from the exceptional signal.

Step 304: determining an exception type corresponding to the second identification information.

Specifically, the second identification information is used to identify the type of exception that occurs in the hardware module. For example, the above-mentioned exception type may be a response error, an integrity error, a timeout error, or a multiplication error.

Step 305: determining an exception processing instruction corresponding to the above mentioned exceptional signal according to the exceptional hardware module and the type of the exception.

For example, assuming that the electronic equipment 100 determines that the exceptional hardware module is an interface module according to the first identification information, the type of exception that occurs in the interface module, for example, a response error, can be determined according to the second identification information. In this way, according to the exceptional hardware module (interface module) and the exception type (response error), it is determined that the exception processing instruction corresponding to the above mentioned exceptional signal can be an instruction to close the interface.

In this embodiment, the electronic equipment 100 may obtain the exceptional hardware module in the neural network processor according to the first identification information obtained from the exceptional signal, and may also obtain the type of the exception occurring in the hardware module according to the second identification information obtained from the exceptional signal, and then the exception processing instruction corresponding to the exceptional signal can be determined according to the exceptional hardware module and the exception type, so that the exceptional hardware module in the neural network processor and the type of the exception occurring in the hardware module can be accurately obtained, then the exception occurring in the hardware module can be processed in time, thereby shortening the error processing delay, and improving the data processing efficiency of the hardware system in the electronic equipment 100.

FIG. 4 is a schematic flowchart of an instruction execution method provided by still another exemplary embodiment of the present disclosure. This embodiment can be applied to the electronic equipment 100. Referring to FIG. 1(a) to FIG. 1(b), the electronic equipment 100 comprises the neural network processor 180.

As shown in FIG. 4, the embodiment of the present disclosure may include Step 401: acquiring a first instruction queue needed to be executed by the neural network processor from an instruction queue buffer in the neural network processor, wherein the first instruction queue comprises a plurality of instructions to be executed sequentially.

Referring to FIG. 1(a)-FIG. 1(b), the first instruction queue can be stored in the instruction queue buffer 160, and the neural network processor 180 can acquire a plurality of instructions needed to be executed from the instruction queue buffer 160 when executing the first instruction queue.

Step 402: determining processing priority corresponding to the exception processing instruction according to the exception processing instruction.

In specific implementation, the processing priority of the exception processing instruction corresponding to the exceptional signal can be set according to the influence degree of the exceptional signal on the processing performance of the electronic equipment 100, so as to ensure that errors that have a greater impact on the processing performance of the electronic equipment 100 can be processed preferably.

Step 403: inserting, according to the above processing priority, the exception processing instruction into the first instruction queue to generate a second instruction queue.

In a specific implementation, in order to ensure the processing performance of the electronic equipment 100, the processing priority of the exception processing instruction corresponding to the exceptional signal may be set according to the influence degree of the exceptional signal on the processing performance of the electronic equipment 100. Specifically, the processing priority of the exception processing instruction corresponding to the exceptional signal that has a greater impact on the processing performance of the electronic equipment 100 needs to be set higher, so that errors that have a greater impact on the processing performance of the electronic equipment 100 can be processed preferentially. For example, assuming that the priority of the instruction to close the interface is higher than the priority of the instruction to shut down the computing unit where the error occurred, then the instruction to close the interface needs to be ranked before the instruction to shut down the computing unit where errors occurred, when the exception processing instructions are inserted into the first instruction queue. Of course, when inserting the exception processing instruction into the first instruction queue, the ranking of the processing priority of the exception processing instruction and the instruction in the first instruction queue also needs to be taken into account. According to the processing priority, the exception processing instruction is inserted into the first instruction queue.

In this embodiment, the processing priority of the exception processing instruction corresponding to the exceptional signal can be set according to the influence degree of the exceptional signal on the processing performance of the electronic equipment 100, thereby ensuring that errors that have a greater impact on the processing performance of the electronic equipment 100 can be processed preferably, and ensuring the normal operation of the electronic equipment 100, which in turn can improve the data processing efficiency of the hardware system in the electronic equipment 100.

FIG. 5 is a schematic flowchart of an instruction execution method provided by still another exemplary embodiment of the present disclosure. This embodiment can be applied to the electronic equipment 100. Referring to FIG. 1(a) to FIG. 1(b), the electronic equipment 100 comprises the neural network processor 180. As shown in FIG. 5, in the embodiment of the present disclosure, the neural network processor may further comprise a first instruction memory, and the foregoing instruction execution method may include:

Step 501: acquiring sequentially instruction storage addresses of a plurality of instructions needed to be executed by the neural network processor in a first instruction memory.

Step 502: sequentially storing the above instruction storage addresses in an instruction queue buffer.

The instruction queue buffer may be a storage unit circuit used to store instruction storage addresses, such as a First Input First Output (FIFO) memory.

Step 503, sequentially numbering the sequentially stored instruction storage addresses to generate a first instruction queue.

For example, assuming that the instruction storage addresses of the plurality of instructions that the neural network processor needs to execute in the first instruction memory are D₀, D₁, D₂, . . . , D_(n), and D₀, D₁, D₂, . . . , D_(n) are sequentially stored in the instruction queue buffer, and then D₀, D₁, D₂, . . . , D_(n) are sequentially numbered as N₀, N₁, N₂, . . . , N_(n) in turn, according to the precedence of storing in the instruction queue buffer. In this way, the first instruction queue is N₀, N₁, N₂, . . . , N_(n).

Further, the neural network processor further comprises a second instruction memory, and a plurality of exception processing instructions are stored in the second instruction memory; in this way, step 403 may include:

Step 504: determining storage addresses of the exception processing instructions in the second instruction memory.

Step 505, storing the storage addresses of the exception processing instructions into the instruction queue buffer.

Step 506, according to processing priority corresponding to the exception processing instructions and the processing priority of the original instruction in the instruction queue buffer, renumbering sequence numbers corresponding to the instruction storage addresses in the instruction queue buffer to generate a second instruction queue.

In this embodiment, after storing the storage address of the exception processing instruction in the instruction queue buffer 160, according to the processing priority corresponding to the exception processing instruction and the processing priority of the original instruction in the instruction queue buffer 160, the instruction storage addresses in the instruction queue buffer 160 are ordered, and then the sequence numbers corresponding to the instruction storage addresses in the instruction queue buffer are renumbered according to the result of the reordering, so that the execution order of the original instructions in the instruction queue buffer 160 can be changed, and the errors encountered by the neural network processor 180 could be processed timely, timely eliminating the already produced impact of the errors on the neural network processor 180, and restoring the normal operation of the neural network processor 180.
